These regions are potentially variable since they are subject to lower selection pressure than the adjacent genes.
These strata are potentially valuable classification variables, and it is likely that the more stratified a population of subjects, the larger the sample size needed for study [22].
This is potentially an endogenous variable, but since the unionization rate differs by occupation, when not controlling for occupation the union instrument might partially capture occupational income, which would invalidate its use.
Oxygen concentration, particularly hypoxia (a state of low oxygen), is potentially an important variable for the developing embryo and stem cells.
Variable selection for Poisson regression when the response variable is potentially underreported is considered.
In all epidemiologic research involving psychological testing, the list of these variables is potentially very long, and researchers appear divided about which to include.
The political variable that is potentially most powerful, and also most uncertain, is the role that Mr. Cuomo will play.
The capacity variables are thus shown to be potentially useful variables for assessing costs in process synthesis exercises.
We also considered the effects of adjustment for the continuous variables birth weight and placental weight and the categorical variables preterm birth and small-for-gestational-age, even though these were potentially intermediate variables.
Nevertheless, there are potentially two variable-related biases, namely selection and recall bias.
Nonetheless, our findings offer initial evidence that could be applied to clinical practice, as coping strategies are potentially modifiable variables.
